Specification of Letters Patent. Patented June 29, 1915.

Application filed September 23, 1907. 7 Serial No. 394,187.

To all whom it may concern Be it known that we, CHARLES F. KETTER- ING and WILLIAM Crmrsr, citizens of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash-Registers, of which we declare the following to be a full, clear, and exact description.

This invention relates to cash registers and has among its objects the improvement of the release mechanism for such machines. It is advisable to retain such machines locked to prevent tampering therewith but some simple method of releasing the ma chine should be employed. In this invention the machine is intended to be released by a depression of the manipulating devices, herein shown as a lever and bank of keys.

An additional object is to provide a re lease mechanism requiring the operation of two manipulative devices before the machine will be finally released. This gives the proprietor an additional check on the opera tions inasmuch as in order to operate the machine the clerk or employee must actuate two different mechanisms.

As the machine is shown, it is adapted to be operated by an electric motor and therefore a further object is to provide an improved circuit closer and clutch mechanism controlled by the machine and adapted to be placed in an ineffective condition near the close of the operation.

A further object is to provide a machine for compelling the operation of the two controlling devices in proper sequence.

With these and incidental objects in view, the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in appended claims and a preferred form of embodiment of which is hereinafter described with reference to the drawings which accompany and form part of this specification.

Of said drawings, Figure 1 is an end elevation of the left hand end of themachine. Fig. 2 is a transverse vertical section showing a bank of controlling keys. Fig. 3

is a rear elevation with the casing partly broken away to Show the motor connection. Fig. i is a detail of the parts shown in Fig. 3 but seen from the reverse direction. These parts comprise the lock arm and the circuit closing lever. Fig. 5 is an end elevation of the motor and the clutch connection. Fig. 6 is a detail of the lock arm shown in Figs. sand 5, and Fig. 7 is a diagram of the motor circuit, i

The inventionlisshown as applied to a well known type of machine now on the market, a complete description of which is to be found in a patent to Cleal and Reinhard, No. 580378, granted April .13, 1897, together with a patent to Carroll, No. 703639,.granted July 1, 1902, but it is to be understood that the invention is applicable to many other types of machines and is shown merely for convenience with the particular type referred to.

The Carroll patent cited shows a multiple counter machine in which the starting lever is adapted to be moved differentially to determine which one of the multiple counters shall be placed in connection with. the operating device. The lever in said patent is arranged to directly release the machine. In

this invention, the same lever is used, al-

though with a slightly different construcquires some little care. If the motor started from the. lever it might easily be that the circuit would be closed before the lever had reached the desired position and a Wrong registration therefore made. By coupling up the motor to the bank of keys and finally controlling the motor from said bank this difficulty is avoided inasmuch as it is an easy matter to depress the proper key quickly. The lever when pinched is arranged to move the arms of a toggle past the center thereby bringing into play a coil spring which tends to move the said toggle and a'lock device to a release position, but

such release is prevented until the depres sion of a key which moves a pin in the key detent out of the path of an arm connected to the toggle. When the pin is so moved the spring may complete the release, at the same time locking thekey from movement machine lever and its attached mechanism is best shown in Fig. 1. This lever 13 is pivoted on the main rod 14 and is provided with a segment rack 15 which is adapted to control the position of the rotatable counter carrier. The counters are not shown, however, as the present invention does not relate particularly to them and another device might be operated by the lever if desired. Mounted on the outward end of the lever is a bent arm 16 with a projection 17 adapted to engage and depress a bar 18 carried by parallel arms 20 which are pivoted on the lever 13. The bar 18 carries a lug 21 adapted to ride on the circular edge 22 of a plate 23, this plate being carried on two connected arms 24 and 25 pivoted respectively rigidly on the shaft 26 and loosely on the pin 27. Outside the path of movement of the lug 21 is index plate 28 having a series of notches, one for each lever position; into any one of which the lug 21 is adapted to move.

It will be seen from the drawing that in order to move the lever 13 it is necessary first to withdraw the lug 21 from the notch in which it happens to be of the index plate 9/8, and this is accomplished by rocking the arm 16 around its pivot and thereby depressing the bar 18. The consequent depression of lug 21 clearly moves the circular piece 23 thereby rocking the arm 24 and its pivot shaft 26. Also rigidly mounted on this shaft is a rearwardly extended arm 31 adapted to engage an anti-friction roller 32 mounted on one of two toggle arms 33 and 34. It will be evident that when the lever 16 is pinched the arm 31 will be slightly elevated and will thereby lift the two toggle arms. The toggle arm 34 is journaled on a pin 35 while the arm 33 is carried by a pin 36 forming a floating pivot.

As seen from the drawing, the straight line from pivot 35 to pivot 36 passes above the connecting pin 37 of the two toggle arms but the movement of the arm 31 before referred to serves to rock the toggle arms so that the pivot 37 is above the straight line joining the pivots 35 and 36 ing crank arm 42 mounted on a stub shaft 43; said crank arm also being engaged with the toggle arm 38 by a link 44 pivoted on the toggle arm at 36. The spring is nor mally under tension and tends to rock crank arm 42 in a clockwise direction as shown on the figure, but such movement is prevented by the toggle. pivot 37 of the toggle is raised above the straight line joining the pivots 35 and 36 the spring 41 can then move the system of levers farther if it were not for mechanism yet to be described.

The link has an upwardly ext-ended arm 46 pivoted at 47 to a crank arm 48 rigidly mounted on a shaft 49. This shaft extends across the machine and, as shown in Fig. 2, in the plane of the key bank has a crank arm 50 having an upwardly extended projection 51. A bank of keys 52 is adapted to finally {release the mechanism by a device now to be described. Each'key is provided with a cam plate 53 which when the key is depressed engages a cam slot 54in a segmental detent 55 and thereby elevates said detent. The detent plate 55 has mounted on a radial arm thereof a pin 56 which in a normal position of the parts is directly above the projection 51 of the crank arm 50.

Clearly when the toggle is raised as above described the spring will move the system of levers thereby rocking the shaft 49 until the projection 51 engages and is stopped by the pin 56 on the detent plate. W hen the key is depressed the pin 56 is carried above the projection 51 and the spring 41 then immediately moves all of the elements connected therewith causing the cutaway section of the crank arm 50 to surround the pin 56 thereby retaining the detent plate 55 in an elevated position and preventing the depressed key 52 from being released.

The rocking of shaft 43 controls the release of the machine and it will be seen that by the construction described a quick move ment of the release arm is provided for. This is of advantage in the type of machine referred to for the reason that a movement of the locking device to release position is entirely out of the control of the operator when once it starts to move. Clearly the crank arm 50 cannot move more than a very slight distance until the detent pin 56 is completely out of its path.

W hen the pin 56 is out of the path of the arm the system of levers immediately moves under force of the spring 41 to complete release position and nothing the operator can do will have any retarding effect on this release movement. The construction also prevents the release of the depressed key after the machine has been released because the release movement of the locking device also causes a positive lock of the key. As the mechanism is shown, there is a two bank control for the machine; that is, to release the mechanism, the lever 16 must be operated and the key 52 must also be de-- When, however, the center inc pressed. This is of advantage in providing a double control over the movements of the operator inasmuch as it is requisite in order to release the machine that the lever be set to cause an operation of thesyst-em and that the proper key 52be depressed in order to provide for indicating some desired characteristic of the transaction.

It is to be noted that no release of themachine should be possible except with the lever 13 exactly in one of its separate positions as it is only in such position that some one of the counters is exactly positioned for operation. To prevent a release of the mechanism except when the lever is properly positioned is the purpose of the index plate 28 and some other parts. The link at as shown in Fig. 1 is provided with an anti-friction roller 61 which is directly in front of the end of the arm 31, vhen the said arm is raised by the pinch lever 16. Clearly therefore if the arm 31 is raised no release ofthe machine will be obtained even by the depression of key 5:? inasmuclras the arm 31 will prevent a rearward movement of the roller 61 and the arm ll carrying the roller. Inorder to release the roller c1 it is necessary to per mit the depression of arm 31 but this is only possible when the lugQl is in position to pass completely into one of the notches of he index plate 28. This mechanism therefore prevents a release of the machine ex cept when the lever is exactly in one of its proper positions.

The construction described compels the proper sequence of operation of the lever and the bank of keys; it being desired that the lever shall be operated first and that the machine shall be finally released by the operation of the key. It will be clear that if the key 52 is first depressed the detent plate 55 will be elevated but no effect will be produced on the locking device inasmuch as the toggle prevents any movement thereof. Moreover, the key will immediately return to its prior position under pressure of the usual key spring as there is nothing to retain the detent plate in its elevated position. When, however, the pinch lever is first operated and the toggle broken, the subsequent depression of a key carries the pin from over the projection 51 allowing a complete release of the mechanism.

before stated, the machine locking device is intended to control the motor clutch and close the electric circuit for the motor contacts where the motor is used. The looking device, however, is clearly applicable to machines in which no motor is used or a Qmachine having amotor of other types than electric. If a motor is used, such for example as a driving belt, the clutch will still be of use although no circuit closer will be necessary. If the crank handle is used, the lock device will still perform its function although neither clutch nor circuit closer is required. It will therefore be understood that although the machine is shown as driven by an electricmotor, the construction is applicable to other types of motor or means for operating the machine by hand.

The electric; motor is mounted on the rear side of the machine and comprises field coils 71 surrounding an armature 72 on a shaft supportinga worm 73. This worm meshes with a large gear 74: which carries a hollow cylindrical part 7 5 forming one of the ele ments of the clutch. The other clutch element comprises the plate 76 rigidly mounted on the sleeve 77 surrounding the bar 78 and said. element is rigidly connected to a bevel gear 7 9 meshed with a second bevel gear 80 mounted on the main operating shaft 81 of the machine. As shown, the bevel gear 80 is twice the size of the gear 7 9 so that two rotations ofthe gear 7 9 and therefore of the clutch, are required to give the requisite one rotation of the operating shaft 81. The shaft 43 of Fig. 1 which is rotated when the key 52 is depressed also carries a crank arm 81., the bifurcated ends of which surround an anti-friction roller 82 on lock lever 83 This lock lever is mounted to rotate about a pin Sat and is provided with an extended arm 85 adapted to-engage a projection movable with the part 7 6 of the clutch and thereby serves to prevent the operationof the machine. It will be seen from Fig. 3 that when the shaft 43 is rotated, the lever83 will rock upwardly and it will thereby release the operating mechanism of the machine.

In cases where the crank handle was used such handle would be connected in place of the clutch part 7 6 so that the movement of the lock lever 83 would withdraw the lock and therefore allow a simple, operation of the handle. The clutch is used to prevent an undue strain on the mechanism at the If, however, the motor is con out any resulting damage to the mechanism.

The connection between the cylindrical part 75 and the cutaway plate 76. of the clutch is accomplished by rollers 87 moving inthe cutaway parts of said plate. This type of clutch is now generally well known. The movement of the cylinder 75 tends to carry the rollers 87 to the narrower parts of the slots in which they are placed thereby rigidly binding together the two parts of the clutch. These rollers 87 are mounted on pins 88 carried by a nearly circular plate 89 mounted loosely on sleeve 77 and capable of a sli 'ht movement relative to the plate 76.

Plungers 89 shown in dotted lines are spring pressed to normally move the rollers 87 toward the narrower parts of the containing slots. The mechanism in Fig. 3 is shown in normal position and it will be clear that when the machine is released in the manner before described, the arm 83 will be rocked around its pivot pin 84 and the locking end thereof carried away from the clutch. As one of the projections of the locking lever 83 is in the path of the plate 89, the withdrawal of the lever will release the springs of the plungers 89 and will force the anti-friction rollers to the narrower parts of their containing slots. If the machine was driven for example by a belt, such belt might be passed around the cylindrical part of the clutch and in such case the described release of the mechanism would immediately lock the clutch parts to gether and cause a complete operation of the machine. As the end of the operation is reached, the lock arm 83 is positively moved back to lock position of the fingers and the projection of plate 89 will finally contact the end 85 of said lever 83 thereby stopping the plate 89. The clutch parts would, however, move slightly forward but inasmuch as this forward movement would press the springs of the plunger-s 89 and move the rollers to the wide parts of their containing slots, the clutch would then be disconnected and the machine stopped although the cylindrical part 75 of the clutch may remain in motion.

The lock relation of the arm 83 with the plate 89 might be depended upon to completely arrest the mechanism but another disk 92 is provided besides said plate 89 and which is movable with the clutch part 76. A projection on this second disk is adapted to be engaged by a projection 93 of the lock arm 83. When an electric motor is used to drive the machine it is of course necessary to close the motor circuit and to accomplish this function, an additional disk 95 is mounted loosely on the sleeve 7 7 and is connected to the plate 92 by a spring 96. This spring passes around the pin 97 on the plate 92 and the pin 98 on plate 95. As shown, the plate 95 has a cutaway portion 99 in which is normally placed an anti-friction roller 100 on the bell crank lever 101 journaled on the pin 102. The plate 95 has fastened thereto a lug 103 one end of which engages in a normal position of the parts with a third projection 10-1 of the lock lever e5 '83 thereby retaining the spring 96 under tension. When the machine is released, le-

ver 83 moves from in front of the lug 103 and the spring 98 will then throw the plate 95 rapidly around until the pin 97 is reached by the other end of the slot 105 in plate 95 in which said pin moves. Clearly this movement of plate 95 will carry the cutaway portion thereof away from the roller on lever 101 and thereby rapidly rotate said lever around its pivot pin. The arm 102 of said lever is adapted to engage the antifriction roller 103" on the circuit closing arm 104 which is pivoted at 105 and carries an insulating strip 106 directly over a spring contact strip 107. When plate 95 is rotated the lever 101 rocks and spring contact 107 is quickly depressed until it engages the stationary contacts 108 thereby closing the motor circuit.

Near the end of the operation lock lever 83 moves downwardly again bringing its projection 104 into the path of the lug 103 thereby stopping disk 95. The cutaway portion 99 of this plate is then opposite the roller 100 but the rocking of the lever 101 is still prevented by lock plate 92 and the circuit is thereby retained closed until the depressed portion of said plate 92 reaches roller 100 whereupon the spring contact 107 rises breaking its circuit and moving the lever 101 so that the roller 100 is again in the cutaway portion of both plates 92 and 95.

It will be clear from the preceding description that in the normal position of the parts both plates 92 and 95 have a cutaway portion opposite the rollers 100 of lever 101 but that when the plate 95 is released by a movement of lock lever 83 the cutaway portion of said plate is thereby carried away from the roller and the circular portion of the plate moves opposite said roller. Even after the clutch has made one complete rotation, the circuit controlling lever 101 is still held in closing position inasmuch as the cutaway portions of plates 92 and 95 are on difi'erent radial lines. At the end of the second rotation of the clutch, however, lock lever 83 is again moved to lock position and the plate 95 held stationary while plate 92 moves up until the original relative position of the two plates is restored and it is only when both depressed portions of the plates 92 and 95 are on the same radial lines that the spring contact 107 may break the circuit. As the mechanism is shown, two rotations of the clutch are necessary at each operation but clearly as many rotations as desired could be had inasmuch as it is the move ment of lock lever 83 to lock position that really controls the breaking of the circuit and not the mere return of plate 95 to its original position.

In order to accomplish the return of the locking device to normal locking position the main operating shaft 81 is provided with a cam 116 shown in Fig. 1 adapted to engage an anti-friction roller 117 on the toggle arm 34: near the end of the rotation of said shaft. When cam 116 engages the roller 117 the locking mechanism will be positively restored to normal position, the toggle arms being moved to depress the center pivot be low the line joining the pivots 35 and 36. The return of the locking device moves the crank arm 50 withdrawing the projection 51 from in front of the detent pin 56, whereupon the key spring together with the detent pin immediately return the detent plate and the depressed keys to their normal position.

It was stated that the mechanism described compelled a proper sequence of operation of the transaction lever and bank of keys. It is possible to depress one of the keys 52 but there is nothing to hold the key detent in adjusted position so that the key spring would cause immediate return of the key to normal position. It would, however, be possible to retain the key depressed and the pin 56 on the segmental detent 55 thereby moved from over the projection 51 of lever 50 and if this was done the pinching of lever 16 would release the mechanism. The same efiect would be produced if a key was held in depressed position at the end of an operation of the machine and the lever 16 again pinched. To prevent such manipulation of the mechanism the crank arm 50 is provided with a pawl 201 as shown on Fig. 2. This pawl is pivoted to the arm 50 at 202 and provided with a spring 203 connecting the pawl and the crank arm and tending to force the pawl into the position of the figure in which the pin 204 on the pawl engages one side of the crank arm 50. The upper end of pawl 201 is provided with a notch 205. The base of the notch 205 is slightly more distant from the center shaft 1% than is the upper end of the projection 51. If a key 52 is depressed, the detent pin 56 will be raised from over the projection 51 but will then be over the upper end of pawl 201 so that even if the lever is pinched the pawl will prevent a. releasing movement of the mechanism. If the lever is pinched first and the key then operated the movement of the toggle past the center due to the arm 31 will permit a rocking of crank arm 50 until the projection 51 engages the detent pin 56. This movement of the crank arm 50 will move the pawl 201 so that its notch 205 is slightly above the base of pin 56. The movement of pin 56 will therefore engage and rock the pawl 201 so that when pin 56 passes above the projection 51 a complete releasing movement may then be obtained. At the end of the operation if the key 52 is held depressed the cam 116, when it restores the toggle, will rockthe crank arm 50 carrying the pawl 201 so that its notch is below the pin 56. If attempt is then made to pinch the lever without releasing the key, the pawl will rise slightly until it engages under the pin 56 producing precisely the position of the parts previously described, and the release mechanism will still be inoperative. The space between the projection 51 and the pawl 20.1 is narrower than the pin 56 so that it would be impossible to depress key 52 and then operate the lever and partly release the key with the anticipation that pin 56 would ride from over the notch 205 on pawl 201 before it obstructs the movement of p awl 51. The pin 56 will, on the contrar move over the projection 51 before it releases pawl 201 and when a sufiicient downward movement is given the pin 56, to completely remove it from the path of pawl 201, the projection 51 will then be under pin 56 and a slight rotation permitted crank arm 50 due to the fact that pawl'205 is at a slightly greater elevation than the projection 51 will permit spring Al to rock the crank arm 50 until projection 51 engages and is stopped by pin 56. It will be seen that this 1 safety pawl 201 eflectually prevents an operation of the mechanism except in the desired sequence.

As the mechanism has been described the circuit for the motor is broken at the end of each operation, although there is no positive stop for the motor. It would therefore follow that the motor would continue to run after the clutch parts have been separated until its momentum was exhausted. Under some conditions especially with alternating g current motors it may be advisable to continue the motor moving between operations. If the motor stops it requires some time to bring it up to speed and as at thistime the whole load of the register is on the motor its acceleration is relatively slow which of course lowers the average speed of operation gram, Fig. 7 may be employed. It will be understood that the motor will not need much current to maintain it at full speed when there is no load thereon. There is provided a shunted resistance around the circuit closer for the motor, this resistance be part, thereby throwing all the line current through the inductive resistance. This will decrease materially the strength of current, but enough will be left to maintain the motor at speed as there is then no load thereon.

The motor circuits are shown in Fig. 7. The power is derived from a battery or other generator 250 from which extend line wires 251 and 252. These may in practice be incandescent light wires or any other c0nvenient power circuit. Connecting with Wire 252 is a lead wire 253 running to a switch 254 of any desired form, though preferably this switch is of some well known snap variety. From the switch a wire passes through a fuse block 255 and a wire 256 to a machine terminal 257. From the other line wire 251 a wire 258 leads to a second machine terminal 259. From terminal 257 a wire 260 leads to the field coils 71 and the armature 72 of the motor which is herein shown as of a series type but may equally well be a shunt or compound wound machine. From terminal 259 two wires lead, one numbered 263 passing to a condenser 26st from the other side of which a wire 265 leads to the contact terminal 108. A second wire 266 from terminal 259 leads to a wire 267 running to contact strip 107 From the field coil 71 a wire 261 leads through a rheostat 262 and a wire 263 to the other contact terminal 107. Across the two terminalsis a shunt comprising wires 268 and 270 with a resistance 269 which for alternating current machines may preferably be of an inductive type as shown in the drawing. During the preceding description of the machine the contact terminal was stated to be single but in reality it comprises two strips 107 and 107 as shown on this figure, the purpose of this double contact being to prevent sparking when the circuit is broken. Assuming the snap switch 254: to be closed as would normally be the case in practice, it will be seen that the motor circuit is complete. This circuit includes the generator 250, wire 252, wire 258, switch 254, fuse block 255, wire 256, terminal 257, wire 260, field coils 71, armature 72, wire 261 rheostat 262, wire 263, wire 270, resistance 269, wire 268, wire 266, terminal 259, wire 258, and wire 251 back to the generator. The current passing will be proportionate to the resistance in the circuit and will be largely determined by the resistance 269. Enough current will pass to maintain the motor at speed as there is no load thereon. When the machine is operated and the circuit closing lever 101 rotated around its pivot 102 the contact terminals 107 and 107 are brought into contact with the plate 108. It is intended that terminal 107 shall engage plate 108 slightly before the contact of terminal 107*. Without tracing the circuits in detail it will be seen It follows from the construction described that the condenser 26& is only in the main circuit for the instant when the spark would occur inasmuch as the contact of terminal 107 with plate 108 almost immediately follows the contact by terminal 107. The use of the shunt resistance 269 is of particular value in connection with alternating current machines. With the shunt resistance for direct current machines and especially for alternating current commutating machines the amount of current passing between operations will be merely enough to keep the speed of the motor up so that it will quickly start the machine when the clutch parts are connected and at the same time the resistance 269 is short circuited by the contact terminals so that the full current passes through the motor causing a quick operation of the machine.

The rheostat 262 is of value in cases where it is desired to use an alternating current motor on a direct current circuit. As the motor is shown it may be used with alternating currents, it being a commutating type motor. Assuming for example that the motor was intended to be used on a 110 volt alternating circuit, if it was desired to use it on a direct current circuit of 110 volts the resistance of the machine would not be sufiicient to keep down the current due to the fact that there would be no inductance caused by the direct current. In this case the rheostat 262 may be employed, thereby cutting down the current enough to run the motor satisfactorily.
